An article on Guru3D outlines the site's frustrations with attempting to create a video card performance comparison using Anno 2070, the latest installment in the Anno series of strategy games. As noted on its Steam page, the DRM in Anno 2070 has an installation limit: "Solidshield Tages SAS 3 machine activation limit," and apparently they ran into this limit by changing video cards in their test rig, leading them to title the article "Why Guru3D probably never will review Ubisoft titles anymore." There seems to be a resolution at the end of all this, as there's an update at the end saying that while the publishing arm of Ubisoft was unwilling to help them with their plight, they contacted Blue Byte, and the Ubi-owned developer of the game was able to unlock the game to suit their review needs.
